Translation: Iguana Tooth

Like all ornithopods, the iguanodontidae were bipedal and herbivorous. Iguanodon, Ouranosaurus, Probactrosaurus, and Vectisaurus.

Translation: Ingenia (an area in Mongolia)
The Ingeniinae (in-JEE-nee-nay) is a subfamily of Oviraptoridae. Unlike several other members of the Oviraptoridae, they did not have crests, and the claws on their second and third fingers were relatively small.

Intelligence of Dinosaurs
Traditionally, dinosaurs have been considered dim-witted creatures, but recent thought is more generous. Evidence suggests that sauropods, which do have rather small brains compared to their bulk, lived in herds and cared for their young. This implies a level of intelligence greater than that of most modern reptiles. Theropods have been found to have relatively large brains with specialized structures, and this argues that they were intelligent in the way that wolves and lions are intelligent.
